BRAKE-HANGER sorronn Application filed January 15, 1927. Serial No.161,415.

My invention pertains to means whereby the brake hangers of railroadcars are pendently supported in place from a portion of the truck frame;the invention having for its object the provision of means adapted tothe use of either the continuous link type of hanger or the U shape typeof hanger, and therefore permits an interchange of hangers. 7

Another object of my invention is to provide retainer elements forholding the hangcrs in place and of such construction that positioningof the hangers may be easily made and removal when necessary as readilyaccomplished; the keeper elements being adapted to receive certain ofthe thrusts encountered by the hangers and therefore taking care of wearresulting from the constant vibration and cillatory movement of thehangers.

Another ob ect of my invention is to provide a construction whereby thehangers or links will be held in proper brake-applying position fortemporary use in the event of loss or misplacement of the keeper elementwhile on the right-of-way, without permitting an improper dropping downof the hanger and therefore of the brakes.

My present invention contemplates an arm or extension preferably cast orformed integral with the truck frame and made to provide a pocket orsocket to receive either the'link "hanger or a hanger supporting pin andmy improved keeper elements; the latter, in conjunction with the pocketor socket forming portions of the arm, being such that lateral orsidewise play of the keeper elements is prevented and also endwisemovement of the hangersupporting pin made impossible.

Another object of my invention is to provide a construction wherebyrotation of the supporting pin when the U-shapehanger is employed, ismade imposslble because of an interlocking relation therewith and as aresult all wear, resulting from vibratory and osa Figure 2 is a verticalsectional view taken substantially on the line 22 of Figure 1 looking inthe direction of the arrows.

Figure 12 is an elevation of a portion of the arm on the truck frame andof the construction shown in Figure 10; the figure showing. the use of'acontinuous link hanger, only a portion whereof is shown. 7

My invention contemplates the use of either the U-shape type of hangershown at 15 in Figure '1 or, the link hanger shown at 16 in Figure 6;the invention involving means whereby thehanger Wlll be securely held in"place while at the same time permitting the necessary oscillatorymovement thereof; Describing the exemphlicationdisclosed in Figures 1 to'5, we find a portionof'the truck side-.fran'ie shown at 17 which, onits inner side and disposed in a direction transversely of theside-frame is provided with an arm 18 preferably integral with theframeand having a top horizontally disposed flange portion 19 which, atpredetermined points in the particular ex- These arcuate portions areintended to. provide suitable spacing or clearance therebeneath toreceive the enlarged eyeleted ends of the Ul-shape link 15 ,when thelatter is employed: The flange portionflg is formed in- I emplii'icationin Fi ure 1, is preferably shown provided with the upwardly disposedarcuate portions 20, 20 arranged coincident with the.

with the arm 18.

flange of comparative width and disposed lattegral with end flangeportions 21, 21 which, in turn, are formed integral with the lower endflange portions 22, 22; the lower end flanges 22 being in spacedrelation with an intermediate lower flange portion 23 arranged inhorizontal alignment therewith. The spacing between the flanges 22, 22and 23 is'suflicient to provide a socket therebetweeu for the sideportions of the hanger 15, or hanger 16 as the case may be, and allowthe necessary oscillatory movement thereof. The lower flanges 22, 22 and23 are shown reenforced by the lips 24: formed integral therewith andThat is to say, a continuous erally from the side of the arm 18 isemployed, being cut away at bottom for passage of the sides of thehanger, to provide an enclosed pocket open on one side toward the wheelsof the truck. 7

The arm 18, at a point intermediate of the arcuate portions 20, 20 andadjacent to the slots or spacings in the pocket for passage of thehanger sides, is provided with the in tegral laterally disposed ribs 25,25, integral with the top and bottom flange portions or pocket walls 19and 23. The upper parts of.

' tures to receive a bolt 30 whereby the retainer 40 or keeper element31, shown in Figure 5, is locked in place; the bolt passing throughanaperture 31 in the keeper.

My improved keeper or retainer element,

shown in Figure 5, comprises an elongated plate, of thicknesscommensurate with: the

vertical width of the pocket on thearm-lS,

with its ends 32, 32 curved or bent towardone side of the longitudinalaxis of the plate and therefore arranged parallel with each other. Theends 32, 32 are preferably shown curved at 33 to provide suitablesockets adapted to receive the enlarged upper eyeleted ends of theU-shape hanger 15 when the latter is employed. The plate or keeperelement 31, intermediate of its ends 32, is

provided adjacent to its bottom with anjupwardly curved lug or lip 34:formed to pro vide a longitudinal socket 35 for reception of thesupporting pin 36 for the U-shape hanger .15 or the upper end of thehanger 16, see

F igure'6. T he keeper element is cut away or recessed at opposite endsof the lip 34 to provide the shoulder portions 37, 37,.see Figure 5,which are adapted to abut against the ribs, 25, see Figure 4. The ends32 of the 'the supporting pin keeper plate are disposed beyond thesockets between the flange portions 22 and 23 of the lower wall of thepocket, namely at the ends of the main portion of the pocket in the arm18. These ends 32 of the keeper plate 31 are apertured at 33 inalignment with the longitudinal socket 35 formed by lip 34 to receive 33of the U-shape hanger 15.

The end walls 21, either one or both, of the pocket, are shown ofl setat 21 in order to provide a small socket at either end, or both ends,ofthe pocket at a point beyond the ends of the main portion of the pocketwhere the ends of the keeper plate are 10- cat-ed. The small pocketorpocketsformed by the off-set 21 is for the purpose of receiving theextended ends 36 of thepin 36.

The extension or ends 36 are non-circular in cross-section and arepreferably of cross-sectional dimensions less than the diameter of themain portion of the pin That is to say, in the particularexempliflcation a segment of the pin at the ends is cut away to providea flat side which engages with the shoulder 39 formed by the off-set 21"of the end walls 21 of the pocket; the socket at the end of the pocketbeing just SUfiflClGfit to receive the reduced end. It is apparent thatthe pin 36, will, therefore, be held against rotation, with the resultthat all wear is confined to the replaceable parts of the sup port,namely to the more inexpensive parts, the pin and the link. the reducedportion of the pin is disposed beyond the shearing-point with the resultI thatthe structure 1s in no way weakened, but

is fully capable to withstand the strains to which it is subjected. Y r

In application, the pin 36 is inserted through the apertures 38 andthrough the eyeleted upper end of the hanger 15 and the pin is placed inthe socket 35 of the curved lip 34 of the keeper plate. The keeperplate, with the suspended hanger, is then'inserted into the pocketdefined by the flange portions 19, 21, 22 and 3; the pin beingpositioned so that ends 36 will enter the sockets at the ends of thepocket with the flat portions bearing against the shoulders 39.

abut a 'a-inst the ribs 25 while the ii 3 34 will extend into the socketor space intermediate of the Vertical ribs 25, see Figures 2 to 4. Thekeeper plate is thus properly positioned and also held against anylateral oscillatory movement.- The locking bolt 30 is then insertedthrough the registering apertures in the pocket defining flange and thekeeper- It is also apparent that WVhen the keeper plate has beenproperly 7 insertedinto place, theshoulders 37, 37 will the upper end ofthe link is placed in the socket of the lip 34 and wear resulting fromoscillations and the downward thrusts will be confined to the link andto the removable keeper element or plate. It is apparent that aninterchange of links may be had with my improved structure without,necessitating alterations. In both constructions the keeper plate withthe suspended hanger is inserted. edgewise into the open side of thepocket disposed toward the wheels of the truck.

With the ribs 25 extending toward the outer edge of the pocket in thearm 18, it is apparent, that in the event of loss or misplacement of thekeeper plate 31, the hanger link or the supporting pin will be held inplace against downward movement and dropping of the brakes below properbraking position therefore prevented, as the bolt 30 will maintain thehanger in the pocket or socket and on the ribs 25 until a replacement ofthe keeper may be made.

In Figures 7 to 12, I show a modification of my invention ,Figures 7 to9 illustrating the use of the U-shape hanger with its supporting pin,while Figure 12 illustrates'the use of the link hanger. I

In this exemplification of theinvention, a portion of the truck frame isshown at 40 and provided with a transversely disposed extension'or arm41 of sufficient thickness to permit being slotted longitudinally on oneside to provide the elongated pocket or socket open toward the wheels ofthe truck, intermediate of the top and bottom bifurcations 42, 43. Inorder to stiffen and reenforce the arm I have shown it provided'with thetop rib 44, while the bottom is provided with the web 45 flaring towardand connected with a vertical portion of the truck frame.

At points coincidentwith the sides of the hangers (which are of more orless standard construction), the arm is slotted transversely to apredetermined extent as at 46, 46, to permit the hangers to bependentlyheld in place and have the necessary oscillatory movement. Inthe particular exemplification, theseslots 46 are also shown disposedslightly beyond the rib'44 in order to provide clearance for theenlarged eyeleted ends of the U-shape hanger, The socket in the arm isalso shown provided with spaced transverse walls or ribs 47 whichreenforce the b furcations; the

ribs being cut away to provide supporting pin or hanger receivinggrooves and to maintain the same in spaced relation with the bottombifurcatlon 43 in order that the keeper plate or element 48 may beintroduced beneath the pin or hanger as the case maybe. 7

The keeper 48 comprises an elongated. plate of thickness commensuratewith the spacing between theupper and lower bifurcations 42, 43, andprovided with transverse slots 49, 49 adapted to register with theslots46 of the arm. One longitudinal side of the plate adformed on the arm;the keeper element 48 and the bifurcations 42, 43 are provided withregistering apertures as at 52, 53, to receive a locking pin or bolt 54,which locks the keeper element in place. e The keeper element atoneorboth ends is provided with a small rib as at 55, partially closing theen-dsof the pin receiving groove; while'the upper bifurcation 42 on thearm, at least at one end, is provided with a fiatsided lip 56, which isadapted to be in alignment with the rib of the keeper element when thelatter is in place; the lip 56 also partially ex tending across the endof the pocket or socket so as toleave a space between lip 56 and the rib55, as shown in Figures 7 and 8.

T he U-shape hanger supporting pin 57 beyond the shearing point, namelybeyond its hearing in the grooved end lug 50 of the keeper element, isprovided with a flat-sided extension 58 (see Figure'7) whichis adapt-'ed to fit into the space between the lip 56 and the rib 55 and as aresult will hold the pin against rotation. i

\Vith this construction, like in the previously described structure,-all wear will be confined to the pin, and the integral portions of thetruck frame or of the arm and the more'expensivekeeper plate will befree of any wear. A seriousobjection to hanger mountings as heretoforeemployed is therefore entirely eliminated, while at the same timepermitting an interchanging of the hangers, themselves, as is apparentfrom Figure 12, where the link type of hanger 16 is shown substitutedfor the U- shape hanger 15 and itssupporting pin 57;

the structure in Figure 12being in every other respect similar to thatshown in Figure 7.

Itis apparent that the rib 55 and the lip 56, like the shoulder '39. inthe construction shown in Figure 1, will hold the pin gainstlongitudinal movement also.

hanger 15 is employed. Figure 6 shows the application of a continuous.link hanger'l6 instead of thew-shape hanger 15 and its sup- 'porting pm36 which; isshown in Figures 1 and 4..
